In the absence, however, of any information as to when, or exactly what, Bleheris wrote, the opinion must, I think, hold the field that the Arthurian saga, as we have it now, is not of Welsh, nor even of pure Breton origin. The Welsh exiles who colonised part of Brittany about the sixth century must have brought with them many stories of the historical Arthur. They must also have brought legends of the Celtic deity Artaius, a god to whom altars have been found in France. These personages ultimately blended into one, even as in Ireland the Christian St. Brigit blended with the pagan goddess Brigindo.(210) We thus get a mythical figure combining something of the exaltation of a god with a definite habitation on earth and a place in history. An Arthur saga thus arose, which in its Breton (though not its Welsh) form was greatly enriched by material drawn in from the legends of Charlemagne and his peers, while both in Brittany and in Wales it became a centre round which clustered a mass of floating legendary matter relating to various Celtic personages, human and divine. Chrestien de Troyes, working on Breton material, ultimately gave it the form in which it conquered the world, and in which it became in the twelfth and the thirteenth centuries what the Faust legend was in later times, the accepted vehicle for the ideals and aspirations of an epoch. *The Saga in Wales* From the Continent, and especially from Brittany, the story of Arthur came back into Wales transformed and glorified. The late Dr. Heinrich Zimmer, in one of his luminous studies of the subject, remarks that “In Welsh literature we have definite evidence that the South-Welsh prince, Rhys ap Tewdwr, who had been in Brittany, brought from thence in the year 1070 the knowledge of Arthur’s Round Table to Wales, where of course it had been hitherto unknown.”(211) And many Breton lords are known to have followed the banner of William the Conqueror into England.(212) The introducers of the saga into Wales found, however, a considerable body of Arthurian matter of a very different character already in existence there. Besides the traditions of the historical Arthur, the _dux bellorum_ of Nennius, there was the Celtic deity, Artaius. It is probably a reminiscence of this deity whom we meet with under the name of Arthur in the only genuine Welsh Arthurian story we possess, the story of Kilhwch and Olwen in the “Mabinogion.” Much of the Arthurian saga derived from Chrestien and other Continental writers was translated and adapted in Wales as in other European countries, but as a matter of fact it made a later and a lesser impression in Wales than almost anywhere else. It conflicted with existing Welsh traditions, both historical and mythological; it was full of matter entirely foreign to the Welsh spirit, and it remained always in Wales something alien and unassimilated. Into Ireland it never entered at all.
